6B-2 ENGINE COOLING
GENERAL DESCRIPTION
COOLING SYSTEM CIRCULATION
During engine warm-up (thermostat closed), the water pump discharges coolant into the water jacket chamber
adjacent to No.1 cylinder. Coolant then flows through the cylinder block and the cylinder heat. Coolant then returns
to the water pump through intake manifold, heater inlet hose, heater unit, heater outlet hose, and water intake pipe.
During normal temperatures (thermostat open), coolant takes the same basic route but is now allowed to flow past
the thermostat, the inlet hose and the radiator, and then back to the water pump through the outlet hose and the
water intake pipe.

THERMOSTAT
A wax pellet type thermostat is used in the coolant outlet passage
to control the flow of engine coolant, to provide fast engine warm
up and to regulate coolant temperatures.
A wax pellet element is hermetically contained in a metal case, and
expands when heated and contracts when cooled.
When the pellet is heated and expands, the metal case pushes
down the valve to open it.
As the pellet is cooled, the contraction allows the spring to close the
valve.
Thus, the valve remains closed while the coolant is cold, preventing
circulation of coolant through the radiator.
At this point, coolant is allowed to circulate only throughout the en-
gine to warm it quickly and evenly.
As the engine warms, the pellet expands and the thermostat valve
opens, permitting coolant to flow through the radiator.
In the top portion of the thermostat, an air bleed valve (1) is pro-
vided; this valve is for venting out the gas or air, if any, that is accu-
mulated in the circuit.

COOLING FAN
The cooling fan is driven by electric motor, and the motor is acti-
vated by ECM / PCM (engine coolant temp.). For its details, refer to
Section 6E.
WARNING:
Keep hands, tools, and clothing away from engine cooling
fan to help prevent personal injury. This fan is electric and
can come on whether or not the engine is running. The fan
can start automatically in response to the ECM / PCM (en-
gine coolant temp.) with the ignition switch in the “ON”
position.

4) Remove thermostat (1).
INSPECTION
1) Make sure that air bleed valve (1) of thermostat is clean.
Should this valve be clogged, engine would tend to overheat.
2) Check to make sure that valve seat is free from foreign matters
which would prevent valve from seating tight.
3) Check thermostatic movement of wax pellet as follows:
Immerse thermostat (1) in water, and heat water gradually.
Check that valve starts to open at specific temperature.
If valve starts to open at a temperature substantially below or
above specific temperature, thermostat unit should be re-
placed with a new one. Such a unit, if reused, will bring about
overcooling or overheating tendency.
INSTALLATION
1) When positioning thermostat on thermostat case, be sure to
position it so that air bleed valve comes uppermost and into the
recession of thermostat case.
2) Install thermostat cap to thermostat case. When installing cap,
align arrow marks on cap and case.
3) Fill cooling system.
4) Connect negative cable.
5) After installation, check each part for leakage.

INSPECTION
Visually inspect fuel lines for evidence of fuel leakage, hose crack
and deterioration, or damage.
Make sure all clamps are secure.
Replace parts as needed.
FUEL TANK
REMOVAL
1) Relieve fuel pressure in fuel feed line according to procedure de-
scribed in Section 6.
2) Disconnect negative cable at battery.
3) Remove rear seat cushion referring to Section 9.
4) Disconnect connectors (1) of fuel tank wire harness.
5) Hoist vehicle.
6) Disconnect fuel filler hose (3) from fuel tank and breather hose
(2) from filler neck (1).

7) As fuel tank has no drain plug, drain fuel tank by pumping fuel
out through fuel tank filler or fuel tank inlet.
Use hand operated pump to drain fuel tank.
WARNING:
Never drain or store fuel in an open container to avoid
possibility of fire or explosion.
8) Disconnect fuel hoses from filter (5) and pipes.
WARNING:
A small amount of fuel may be released after fuel hose is
disconnected. In order reduce the chance of personal in-
jury, cover hose and pipe to be disconnected with a shop
cloth. Be sure to put that cloth in an approved container
when disconnection is completed.
9) Remove fuel tank from vehicle.
INSPECTION
After removing fuel tank, check hoses and pipes connected to fuel
tank for leaks, loose connections, deterioration or damage. Also
check for leaks from installation face of parts installed on fuel tank,
visually inspect fuel tank for leaks and damage.
Replace any damaged or malconditioned parts.
INSTALLATION
1) Install fuel pump assembly to fuel tank.
Use new gasket.
2) Install 2-way check valve to fuel tank directing its black nozzle
toward fuel tank.
3) Connect hoses and pipes to fuel tank.
4) Connect breather hose to fuel tank.
5) Install fuel tank to vehicle.

7) Connect fuel hoses to filter and pipes.
8) Connect connectors of fuel tank wire harness.
9) Install rear seat cushion referring to Section 9.
10) Connect negative cable at battery.
11) With engine “OFF” and ignition switch “ON”, check for fuel
leaks.

6E1-4 ENGINE AND EMISSION CONTROL SYSTEM (TBI FOR G10)
The main components of this system are fuel tank,
fuel pump, fuel filter, throttle body (including fuel injec-
tor, fuel pressure regulator and idle speed control ac-
tuator), fuel feed line, fuel return line and air cleaner.
The fuel in the fuel tank is pumped up by the fuel
pump, filtered by the fuel filter and fed under pressure
to injector installed in throttle body. As the fuel pres-
sure applied to the fuel injector (the fuel pressure in
the fuel feed line) is always kept a certain amount
higher than the pressure in the intake manifold by the
fuel pressure regulator, the fuel is injected into the
throttle body in conic dispersion when the injectoropens according to the injection signal from ECM.
The fuel relieved by the fuel pressure regulator re-
turns through the fuel return line to the fuel tank.
The injected fuel is mixed with the air which has been
filtered through the air cleaner in the throttle body. The
air/fuel mixture is drawn through clearance between
throttle valve and bore.
Then the intake manifold distributes the air/fuel mix-
ture to each combustion chamber.
For the structure and operation of the fuel tank and fil-
ter, refer to SECTION 6C “ENGINE FUEL”.
